I'm pretty much an incrementalist, and think it best to make small steps in the desired direction. How about we first try free, no incentive, sterilization, and see how that works out. If it turns out that it does not reduce welfare families, or abortions as we wish, then we can incentivize.

How about if we paid for NONE of it... That would be cheaper for everyone involved except those RESPONSIBLE. Once they figure out that there are consequences for their irresponsible actions, this would slow back down to the levels of the 1950s...
